Beyoncé is in Europe for her "Mrs. Carter World Tour," which kicked off last month in Belgrade, Serbia, and closes August 5 at the Barclays Center in Brooklyn. The North American leg begins June 28 in Los Angeles.

The butt-slapping incident sparked heated debate online, with some people saying Beyoncé should have expected it.

But others bashed the excited fan, arguing that his actions encourage misogynistic behavior as a society.

"I'm disappointed that she didn't at least have him kicked out — arrested would have taught him a better lesson," someone else posted. "Everyone always passes all this misogynistic behavior against Hollywood's celebrities by paparazzi AND fans off. It ISN'T harmless — it only makes us more complacent and dysfunctional as a society, and it teaches our young girls that it's okay for men to consider them a piece of meat. Beyoncé is obviously a lot more than that, and she deserved more respect."
